Automatically Entering a Parameter Value In Access

I have a query that when you run it you get an Enter Parameter Value window.  I want to run this query along with several others in a macro and I don't want to have to enter this value every time I run the macro.  Is  there a way to automatically populate the value as the macro runs the queries?  Please advise and thank you very much.

If you are always going to use the same value then chnage the query to use that value instead of using a parameter field.

There are some things to note:
1) The use of the "PARAMETERS" keyword in the query itself
2) You can get a count of a query's parameter's by referencing the parameters.count property
3) You can refer to a query's parameters as a collection(by name) or index(by number)

Public Sub PQry()
Dim DB As Database
Dim Q As QueryDef
Dim I%
Set DB = CurrentDb
Set Q = DB.QueryDefs("pquery")
Debug.Print Q.Parameters.Count

For I = 0 To Q.Parameters.Count - 1
Debug.Print Q.Parameters(I).Name, "'"; Q.Parameters(I).Value; "'"
Q.Parameters(I).Value = "10101"
Debug.Print Q.Parameters(I).Name, "'"; Q.Parameters(I).Value; "'"

Next
End Sub




The code snippet below was taken from the Access 97 help file on PARAMETERS:


This example requires the user to provide a job title and then uses that job title as the criteria for the query.
This example calls the EnumFields procedure, which you can find in the SELECT statement example.
 
Sub ParametersX()
 
	Dim dbs As Database, qdf As QueryDef
	Dim rst As Recordset
	Dim strSql As String, strParm As String
	Dim strMessage As String
	Dim intCommand As Integer
	
	' Modify this line to include the path to Northwind
	' on your computer.
	Set dbs = OpenDatabase("NorthWind.mdb")
	
	' Define the parameters clause.
	strParm = "PARAMETERS [Employee Title] TEXT; "
 
	' Define an SQL statement with the parameters
	' clause.
	strSql = strParm & "SELECT LastName, FirstName, " _
 
& "EmployeeID " _
		& "FROM Employees " _
		& "WHERE Title =[Employee Title];"
	
	' Create a QueryDef object based on the 
	' SQL statement.
	Set qdf = dbs.CreateQueryDef _
		("Find Employees", strSql)
	
	Do While True
		strMessage = "Find Employees by Job " _
			& "title:" & Chr(13) _
			& "  Choose Job Title:" & Chr(13) _
			& "   1 - Sales Manager" & Chr(13) _
			& "   2 - Sales Representative" & Chr(13) _
			& "   3 - Inside Sales Coordinator"
 
intCommand = Val(InputBox(strMessage))
		
		Select Case intCommand
			Case 1
				qdf("Employee Title") = _
					"Sales Manager"
			Case 2
				qdf("Employee Title") = _
					"Sales Representative"
			Case 3
				qdf("Employee Title") = _
					"Inside Sales Coordinator"
			Case Else
				Exit Do
		End Select
		
		' Create a temporary snapshot-type Recordset.
		Set rst = qdf.OpenRecordset(dbOpenSnapshot)
 
' Populate the Recordset.
		rst.MoveLast
			
	' Call EnumFields to print the contents of the 
	' Recordset. Pass the Recordset object and desired
	' field width.
		EnumFields rst, 12
	Loop
	
	' Delete the QueryDef because this is a
	' demonstration.
	dbs.QueryDefs.Delete "Find Employees"
	
	dbs.Close
 
End Sub

Oops, you said macro not VB, I spoke too soon

You could create a form with a text box and have the query reference that text box.
The text box can be bound to a table if you want to keep the same criteria for a while (days, weeks, months)
 or the text box can be unbound if you want the criteria to only be stored for the limited time that the form is open.

You would create a form with a text box on it and name the text box something appropriate like maybe "Text0"
In your parameter query, put a reference to that form's text box instead of the parameter.
That would look something like this: [forms]![formname]![text0]
Whenever you ran the query it would look for the textbox on the form and filter your query with that.
You could use multiple text boxes to filter multiple fields if you wanted.
This works well if you have multiple queries that filter on the same criteria.
A little complicated but, this will work.

I had this same need... I wanted to run 4 queries, each with the same parameter.  I ended up doing the following:

1.  Created a form to get the parameter
- I named the form SelectForm
- in my case, I wanted to select a field from an existing table, so I used a combo box that selected the field I wanted to pass.
- I named the field SelectParameter

2.  Modified the queries I ran to accept the value from the form I just created.
- in criteria for each query, I put =[Forms]![SelectForm]![SelectParameter]

3.  On the SelectForm form I created, I put a command button to run each of the queries.

4.  I can now run the form, select the value I want, and it runs all 4 queries.  You can add some fancier stuff to turn off the messages and look for errors, but I was happy just to get this far.
